Abstract: This report documents the theory and implementation of the bidirectional reflectance distribution function (BRDF) developed for the Countermine Computational Testbed. The purpose of the BRDF is to capture the directional effects of reflection as controlled by the incident energy direction, the sensor direction, and the surface orientation. In addition, the BRDF breaks the reflected energy down into its principal polarization modes as incident energy can be multi-spectral and polarized. The code can be used to interpret the results of spectral reflectance measurements and to predict the degree of polarization of a variety of surfaces. After an introductory description of the physical principles governing the reflection of electromagnetic energy, this report documents the sources of relationships used in the computer code, compares the published data and predictions made by the routine, and performs parametric studies to investigate specific details of responses that are of particular practical interest.
